Subject: actors: Switch out address objects for more-easily-serialized cons cells
X-Git-Tag: v0.2.0~62
X-Git-Url: https://jxself.org/git/?a=commitdiff_plain;h=89dfbd6214e8e00bca235fd2974c0b343655d48f;p=8sync.git

actors: Switch out address objects for more-easily-serialized cons cells

This is maybe temporary.  If we ever have canonical sexps as the
general serialization format, or something like that, we might revert
to a nicer structure.

* 8sync/systems/actors.scm (<address>): Commented out.
